摘要

Aramid nanofibers are used to enhance the anti-swelling and mechanical properties of hydrogels.

Abstract

Hydrogels are widely employed in various cutting-edge fields due to their excellent flexibility and tunability. However

hydrogels undergo significant swelling when immersed in seawater or other ionic solutions

leading to a severe decline in their performance. Herein

we develop a composite hydrogel (PAH) with anti-swelling capability in different solution environments

constructed through hydrogen bonding interactions between rigid aramid nanofibers (ANF) and flexible poly(vinyl alcohol) (PVA). The dense three-dimensional skeleton within PAH not only dissipates energy to enhance its strength and toughness but also effectively inhibits water molecule penetration. Even after immersion in different ionic solutions

PAH maintains its structural integrity (equilibrium swelling ratio of only 0.1%)

while retaining excellent mechanical properties. This work provides a simple and effective strategy for improving the anti-swelling ability of hydrogels in different solutions

offering insights for broadening the application scope of hydrogels.
